Nerval's Lobster writes: "AMD, Intel, ARM: for years, their respective CPU architectures required separate sockets, separate motherboards, and in effect, separate servers. But no longer: Facebook and the Open Compute Summit have announced a common daughtercard specification that can link virtually any processor to the motherboard. AMD, Applied Micro, Intel, and Calxeda have already embraced the new board, dubbed “Group Hug.” Hardware designs based on the technology will reportedly appear at the show. The Group Hug card will be connected via a simple x8 PCI Express connector to the main motherboard. But Frank Frankovsky, director of hardware design and supply chain operations at Facebook, also told an audience at the Summit that, while a standard has been provided, it may be some time before the real-world appearance of servers built on the technology."
